Sometimes, bugs in your code can prevent you from accessing your Project. For example, if you have an infinite loop in your JavaScript, the browser can freeze or crash.

If you run into that kind of problem, you can cancel rendering with this URL parameter:

?cancel_render=true

Add that to the end of your Project URL and you'll be able to edit your project.

You'll see a "Render Cancelled" message in the preview window while rending is off.

When you're ready to let the Project render again, click the "I'm ready to render!" button.
